Atmospheric lubricator



JOHN SUTTON, OF

NEN YORK, N. Y.

SELF-FEEDING ATMOSPHERIC LUBRICATOR.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, JOHN SUTTON, of New York, in the county of New Yorkand State of New York, have invented a new and improved mode ofconstructing a selffeeding atmospheric oil-cup for lubricating journalsof shafts, crank-pins, guides, and, in fact, all working joints of everydescription of machinery requiring lubrication, the object being toeconomize the oil and keep the part well and regularly supplied duringthe time it is in motion, it being so regulated thatby the revolution ofthe journal the oil will be drawn to the same from the reservoir, and bythe inaction of the journal or other part the oil will stop flowing; andI do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this speciiication,in which the figure is in part perspective and in part a transverseview.

A, is the oil reservoir made of any suitable material, shape or size,which with its tube a, and shank Z9, and part cover b, may be made orcast in one piece, or separately and jointed as required, or thereservoir A, and part cover may be cast with the pillar block z', andthe tube a, and Z), inserted and its regulating cap attached as may berequired, the tube a, standing within the reservoir A, being for thepurpose of preventing the sediment going to t-he working part. The lowerextremity of the tube or shank 7J, may be continued down and screwedinto the brass box y', in red lines, thus conveying all the oil to thepart, or it may be connected as required to the pillar block cap z', yetin this case much oil is lost by escaping between the cap and box j.

c, is the opening or neck-of the reservoir A, for receiving the oil.

f, is a channel cut outside of the neck c, in the part cover b', ofreservoir for catching any surplus drops when filling (yet this is notreally essential). Vhen it is necessary to make the reservoir for largejournals Src., with compartments, it may have one or more regulatingcaps, also one or more tubes or Shanks.

B, O, D, is the combined regulating arrangement, B, serving as the coverof the reservoir A. Within its underside is an elastic washer d,securely tted 1n, having 13,769', dated November 6, 1855.

a passage e, cut in its center, also through the cover B, to the spaceE, for air. Into the upperside or top of cover B, is a vertical threadedchamber into which is loosely inserted the regulating plug D, having aspace E, under it for receiving any suitable porous and elasticsubstance fitted in loosely which on being compressed by screwing downthe plug D, will diminish the passage of the air to the reservoir A, andby a reversion of the plug D, will enlarge the same so that beinggraduated to suit it cannot admit more or less air to t-he reservoirthan it is required to, which air passes through the passages e, e,-porous substance &c., and fills the vacuum that is made as the oil isdrawn from the reservoir A, by the working of the part under it.

O, is a dome or guard screwed to the top of the cover B, for preventingany injury to or displacement of the regulating plug D.

e, is a small passage in the dome from the atmosphere to its interiorfor the admission of air a suliiciency finding its way between thethreads of the plug D, &c., to the space E, or substance, or ifrequisite the plug D, may be drilled or channeled. If required, .as itmay be in some cases, the plug D, may be dispensed with and the top ofcover B, made solid, having the passage e, continued to the top of samebetween which and the underside of the dome C, may be placed the porousand elastic body the quantity of air through which may be regulated bytightening and slackening the dome as shown by the plug D.

Mode of operating: Determine the number of drops of oil required per dayfor the part, select a feeder holding that quantity, put a washer g, onthe shank end and attach it to the brass box-bush or other part, so thatit shall be a Xed air tight joint, see that t-he cap B, has its elasticwasher d, remove the dome O, and regulating plug D. In the space E,place a flat circular piece of gutta percha, cork, or rubber, having cuta small channel across its under face. rlhen put in loosely circularpieces of cloth above it, screw down the regulating plug D, tightly withthe fingers, fill the reservoir through the neck c, with oil, put on thecap B, &c., as now combined, screwing it tightly with the lingers. Nowshould it feed too much tighten the plug D, more, thus shutting off theair or slacken it if not feeding enough until it delivers to suit,

when the dome C, may be screwed to its seat as it is no w in workingorder. It will be necessary to fill this cup but once per day and soregulate it that at the end of the working time it will have deliveredall its oil. Yet in many cases when there is a quick revolution of thejournal in the direction of the arrow 7c, this apparat-us being attachedas shown in the drawing having its regulating plug screwed down justenough to prevent the oil dropping. Then the journal is still it may beseen that the oil (in the passage L, and channel zf, cut in the brassboX, and resting on the journal) will be drawn from the reservoir A, asthe shaft revolves, thereby creating a vacuum in the reservoir which isfilled by the atmosphere passing through the passages, &c., to thereservoir so that when t-he machine is not working should there be anyoil in the reservoir it cannot escape until again drawn upon by theworking of the part. For ocean Steamers for certain parts t-he reservoirmay be constructed to hold and feed suflicient for the passage.

I am aware of there being in use self feeding oil cups for lubricatingjournals, &c., of machinery, having working buckets or valves, withinthe reservoir, with outside connections operated by the shaft. I am alsoaware there are others of the valve under the reservoir, and working inthe oil, the objection to all of which is their complication andliability of derangement, and irregularity in feeding, by the valves,plugs, &c., becoming corroded or gummed.

W'hat I claim as my invention and desire to secure by Letters Patent is-An arrangement of means constructed on or within the cap or cover B, (ofthe reservoir co-ntaining the oil or other lubricating material)sufficiently distant from the oil to never be in contact with the same,by

the adjusting of which, the passage or passages leadmg from thereservoir to the atmosphere may be entirely or partially openedorclosed, at will, thus causing an plug D, and the substance in the spaceE,

as a hollow, or other plugv or equivalents may be used to produce thesame effect, either of which, may be used as the part whenplaced maypermit, and without al` tering the principle or mode of feeding hereindescribed.
